“…The percentages of good/poor sleepers found in sample 2 according to the PSQI and the mean overall PSQI score (see instruments section) were similar but systematically lower compared to those reported in many other studies with university student samples (Carney et al, 2006;Cheng et al, 2011;Clegg-Kraynok et al, 2011;Kabrita et al, 2014;Lemma et al, 2012Lemma et al, , 2013Lund et al, 2010). This suggests that sample 2 does not over represent poor sleepers, so it is not biased in in this sense.…”

Based on successive samples totaling more than 5000 higher education students, we scrutinized the reliability, structure, initial validity, and normative scores of a brief selfreport 7-item scale to screen for the continuum of nighttime insomnia complaints / perceived sleep quality, used by our team for more than a decade, henceforth labeled the Basic Scale on Insomnia complaints and Quality of Sleep (BaSIQS). In study/sample 1 (n = 1654), the items were developed based on part of a larger survey on higher education sleepwake patterns. The test-retest study was conducted in an independent small group (n = 33) with a 2-8 week gap. In study/sample 2 (n = 360), focused mainly on validity, the BaSIQS was completed together with the Pittsburgh Sleep Quality Index (PSQI). In study 3, a large recent sample of students from universities all over the country (n = 2995) answered the BaSIQS items, based on which normative scores were determined, and an additional question on perceived sleep problems in order to further analyze the scale's validity.Regarding reliability, Cronbach alpha coefficients were systematically higher than 0.7, and the test-retest correlation coefficient was greater than 0.8. Structure analyses revealed consistently satisfactory two-factor and single-factor solutions. Concerning validity analyses, BaSIQS scores were significantly correlated to PSQI component scores and overall score (r = 652 corresponding to a large association); mean scores were significantly higher in those students classifying themselves as having sleep problems (p < .0001, d = 0.99 corresponding to a large effect size). In conclusion, the BaSIQS is very easy to administer, and appears to be a reliable and valid scale in higher education students. It might be a convenient short tool in research and applied settings to rapidly assess sleep quality or screen for insomnia complaints, and it may be easily used in other populations with minor adaptations.

“…Studies in the United States and Argentina indicate that this behavior may be common among freshmen and medical students, as they reserve sleeping times to study and finish their academic activities. [35][36] Thus, instead of using hypnotic meds, it is important for students to try and adapt their daily reality, in order to solve the lack of coordination in their circadian rhythm and, to the extent possible, to comply with their academic and professional obligations. To give an example, changing class times is impossible, but trying to sleep earlier the night before and fleeing from stimulating foods, substances or behaviors are options within these young people's reach.…”

“…12,15,[17][18] When considering foreign publications, the same fact was repeated: all manuscripts found showed lower percentages of bad sleep quality among college students, ranging between 9.8% and 89%. 3,13,26,30,32,[35][36][37] Unfortunately, this discrepancy cannot simply be attributed to cultural differences among the student samples, as all studies used in the comparison adopted the same instrument, the PSQI. Moreover, the studies undertaken in Brazil also showed much lower results.…”

ABSTRACT:The aim in this research was to evaluate the sleep quality of college students in Fortaleza, Ceará, Brazil. A crosssectional study was conducted with 701 students from the Universidade Federal do Ceará, from March to June 2011. We used the Pittsburgh Sleep Quality Index (PSQI). Most students presented poor subjective sleep quality (54%), sleep latency in less than 15 minutes (60.1%) and efficiency under 65% (99%). In the sample, the sleep duration was of 6.3 hours per day (SD±1.4 hours) (p<0.001). Data analysis revealed that a substantial portion of the college students (95.3%) surveyed presented poor sleep quality. It is essential to operationalize health promotion actions at the universities in such a way that the students construct their own quality of sleep. DESCRIPTORS: EVALUACIÓN DE LA CALIDAD DEL SUEÑO DE ESTUDIANTES UNIVERSITARIOS DE FORTALEZA-CERESUMEN: El objetivo de esta investigación fue evaluar la calidad del sueño de los estudiantes universitarios en Fortaleza, Ceará, Brasil. Se realizó una encuesta con los estudiantes de 701 en la Universidad Federal de Ceará entre marzo y junio de 2011. Se utilizó el índice de la Calidad del Sueño de Pittsburgh (PSQI). La mayoría de los estudiantes tenía una mala calidad subjetiva del sueño (54%), la latencia del sueño y la eficiencia de menos de 15 minutos (60,1%) y 65% (99%), respectivamente. La duración del sueño de la muestra fue de 6,3 horas por día (SD ± 1,4 horas) (p<0,001). El análisis de los siete componentes del PSQI mostró que una parte sustancial de los estudiantes universitarios encuestados (95,2%) tienen mala calidad del sueño. El análisis de datos reveló que una parte sustancial de la universidad investigado (95,3%) tenían mala calidad del sueño. DESCRIPTORES:Sueño. Transtornos del sueño. Estudiantes. Enfermería.

“…Commonly stated reasons for using stimulants included improving work performance and concentration, even though stimulant usage has been associated with lower grade-point averages. 26,27 Given the increased consumption of energy drinks among college students and the limited studies 6 that evaluate their possible adverse impact on sleep disorders among young Peruvian adults, we conducted this study to evaluate patterns of circadian rhythm characteristics and daytime sleepiness and to examine the extent to which the consumption of caffeinated beverages is associated with the evening chronotype and daytime sleepiness among Peruvian college-age students.…”

Objectives: The aims of this study were to evaluate patterns of circadian preferences and daytime sleepiness, and to examine the extent to which the consumption of stimulant beverages is associated with daytime sleepiness and evening chronotype among Peruvian college-age students. Methods: A total of 2,581 undergraduate students completed a self-administered comprehensive questionnaire that gathered information about sleep habits, sociodemographic and lifestyle characteristics, and the use of caffeinated beverages. The Morningness-Eveningness Questionnaire (MEQ) and Epworth Sleepiness Scale (ESS) were used to assess chronotype and daytime sleepiness. We used multivariable linear and logistic regression procedures to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for the associations of sleep disorders with sociodemographic and behavioral factors. Results: The prevalence of daytime sleepiness was 35% [95% CI 32.7-36.4] and eveningness chronotype was 10% [95% CI 8.8-11.1%]. Age, sex, cigarette smoking, and alcohol consumption were significantly associated with an evening chronotype. After adjusting for age, sex, smoking, body mass index, and physical activity, students who reported consumption of any stimulant beverages had 1.25 increased odds of excessive daytime sleepiness (OR = 1.25 [95% CI 1.03-1.53]) compared with students who did not consume stimulant beverages. Consumption of any stimulant beverages was not statistically significantly associated with being an evening chronotype (OR = 1.30 [95% CI 0.86-1.96]). Conclusions: Excessive daytime sleepiness and eveningness chronotype are common among Peruvian college students. MEQ scores were associated with age, sex, smoking, and alcohol consumption. Regular stimulant beverage consumption tended to be positively associated with excessive daytime sleepiness.
